By this means, any tendency for a careless operator to change the scale of the meter It is conceivable that various structural modifications may be effected within the scope of my invention, and I desire that only such. limitations shall. be imposed as are indicated in the appended claims.

I claim as-my invention:

1. In a switching device, the combination with a rotatively and axially-adjustable rod and a single contact member projecting laterally therefrom, of a plurality of stationary contact members disposed circumfercntially in substantially the same plane to be severally engaged by the movable contact member and serving as stops therefor, and means for preventing full axial adjustment of said rod to close the switch except when the contact members are inoperative angular relation.

2. In a switching device, the combination i with a rotatably mounted and axially ad justable rod, and a single contact arm projecting laterally from said rod, of a plurality of stationary contact members arranged substantially in the arc of a circle and in substantially the same plane to be severally engaged by said contact arm and serving as stops therefor, of resilicntmeans for normally holding the movable contact. member out of engagement with the stationarycoir tact members, and means "tor preventing full axial movement of said rod to close the switch except when the contact members are in operative angular relation.

3. In a switching device, the con'ihination with a rotatably mounted and axially adjustable rod, and a resilient contact member projecting laterally from said rod, of stationary contact members arranged substantially in the arc of a circle arid in substantially the same plane to be severally engaged by said contact arm and serving as stops therefor, of means for separating thecontact members, means for preventing full axial movement of the contact-bearing rod to close the switch except when the movable contact member is in front of a stationary contact member and for locking the contact memhers in engagement.

lpln a switching device, the combination with a rotatably mounted and axially adjustable rod, and a resilient-contact member projecting laterally from said rod, stationary contact members arranged substantially in the arc of a circle and in substantially the same plane to be severally engaged by said. contact arm and serving as stops therefor, of a spring for separating the contact members, means for permitting full axial movement of the contaet-bearing rod to close the switch only in the contact positions of the contact members and for locking them in engagement with each other in said positions when full axial movement of said rod. is effected.

5. In a switching device, the combination with 'aninsulating plate, plurality of stationary contact members secured thereto and arranged substantially in the arc of a circle, a contact-bearing rod extending through the plate and rotatably mounted thercimn resilient contact member projecting laterally from the rod and adapted to engage the sta tionary members, an operating knob at one extremity of the rod, a stationary hearing at its opposite extremity, and a spring interposed between the contact arm and the stationary bearing and tending to separate the contact members, of a cross pin secured to the rod between the contact arm andthe insulating plate, said plate having a cylindrical recess for the pin, plates located in the outer end of the recess and having cruciform slots to receive said pin. the slot in the outer plate being wider than that in the inner plate in order to hold the contact; members in engagement in each of. the operative positions of the switch.

6. In a switching device, the combination with. an insulating plate" having a recess in one. face, aplurality of stationary Contact members secured to said plate and disposed around said recess, a rod rotatal'ily mounted in said plate, a contact arm projecting latorally from said rod and adapted to engage the several stationary contact mei'nl'iers, an operating knob at one end of the rod a stationary bearing for the opposite end of the rod and a spring interposed bet ween the contact arm and the statiomiry bearing,- of a cross pin secured to the rod Within the recess in the insulating plate, plateslocated in the outer end of the recess and having cruciformv slots to receive said pin, the slot in the outer plate being wider than that in the inner plate in order to hold the Co t ct members in engagement in each of the circuit-closing posit ions of the contactarm.

In testimony whereof, l have hereunto subscribed my name this 31st day of Dec, 1907.
